SEECIFICATION forming part of Letters Patent No. 675,542, dated June 4,1901. Application filed July 28,1900. Serial No. 25,077. (N mod To aZZwhom, it may concern.-

Be it known that I, FRANK R. OoAr'Es, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Rail-Joints, ofwhich the fol= lowing is a specification.

My invention relates to certain new and useful improvements in jointsfor railway- 1o rails, and has particular reference to novel lockingmeans for securing the parts together.

The object of my invention is to provide a simple and effective lockin gdevice for fastening together in a permanent manner the parts of arail-joint embodying a base or shoe plate and which will not becomeloosened by the vibration and pounding to which the rails are subjected,but always remain in the locked position to which it has been adjusted.

With these and other ends in view I have illustrated myinvention in theaccompanying drawing, which shows a rail-joint comprising a railA, thean gle-plates B C, arranged on opposite sides of the web D of the railand engaging with the head E and base F of the meeting ends of tworails, a base or shoe plate G, having an upright leg I and a bolt I,pass ing through openings 5 0 cl h in the angleplates, the web, and theupright leg, and fastening the parts together. This bolt is usuallyprovided with a nut J, which frequently works loose, owing to thevibration of the rails and other causes, and permits the parts toseparate in a manner which is liable to result in serious consequences.

Itis my object to secure the boltfroln working loose and provide apermanent lock for the parts; and this I accomplish in a very simple andinexpensive manner by providing 0 a screw-threaded connection betweenthe bolt, the leg, and one of the angle-plates, the nut J thereuponacting as a jam-nut and making a permanent lock.

The bolt is provided with a head K and is threaded, preferably, forabout half of its length, so that the angle-plates can be drawn uptightly against the rail, and the nut J is then screwed on the end ofthe bolt against the upright leg. I may thread the bolt-openings be ofeither of the angle-plates or thread alternate openings in both plates,so that of the four bolts usually employed two will be screwed into onean gle-plate and two into the other. I

It will be observed that my invention adds very little to the usual costof manufacturing rail-joints, but at the same time it pro Vides forsecuring and permanently locking the parts together.

I do not limit the application of my inven- 66 tion to the particularkind of rail-joint herein shown or to any special rail, angle-plates, orbase-plates, as, so faras I am aware, it may be employed with any typeof joint having angle or fish plates and a base or shoe plate of anykind. The thread is out far enough up on the bolt to enable it to betightened up whenever it may be necessary.

Having thus fully described my invention, what I claim, and desire tosecure by Letters 70 Patent, is-'- In a rail-joint, the combination witharail,

of angle-plates on opposite sides of the rail, a base or shoe platehaving an upright leg on one side thereof, a bolt passing through.openings in the rail, the angle-plates and the upright leg and having ascrew-threaded connection with the leg and its adjacent angleplate, anda nut on the end of the bolt, sub stantially as described.
